AUTOMATIC WHISTLE-OPERATING MECHANISM.

$PECIFICATION forming part of Letters Patent No. 759,257, dated May 10, 1 904.

' Application filed an ary 18, 1904. Serial No, 189,550. (No model.)

To all whom it may concern:

Be it known that I, ORR (lFIsnuR, a citizen of the United States, residing at Delphos, in the county of Ringgold, State of Iowa, have invented certain new and useful Improvements in Automatic histle-Operating Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to whistling mechanisms; and it has for its object to provide a construction and arrangement through the medium of which when a railroad -train is passing a certain point its whistle will be antomatically operated.

A further object of the invention is to provide a construction of this nature which will not only be cheap and simple, but eliieientin its operation.

In the drawings forming a portion of this specilication, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation showing-a portion of a locomotive and of a railwaytraok equipped with the present invention. Fig. 2 is a detail perspective view of the operating-lever. Fig. 3 is a detail perspective view of the hanger for the lever. Fig. 4 is a detail view showing a portion of the truck of the locomotive with the snow-plow and leverguide attached thereto. Fig. 5 is an enlarged view showing the portion of the engine-truck with the lever and other parts connected thereto.

Referring now to the drawings, there is shown a portion of a railway in which the rails are secured to ties 11 in the usual manner. At the side of the track and upon the end portions of the ties are secured brackets 11, which support a rail 12, that is of a length corresponding to the time the whistle is to be sounded, the ends of the rail 12 being curved downwardly below the surface of the track-rail, while the intermediate portion thereof projects above the track-rail.

To the cross-beam 13 of the truck of each locomotive is connected a U-shaped hanger 14, through the central portion of which is passed a bolt 15 upwardly through the beam 13. A lever 16 is pivoted at a point between its ends upon a pin 17, engaged through the sides of the hanger, said lever consisting of a broad bar the rear end portion of which is given a quarter-twist, so as to lie transversely above the rail 12, this latter portion of the lever being curved slightly and extending rearwardly from the pivot, so that it will strike the downturned end of the rail 12'and drag therealong onto the central portion and thence along it to the opposite end of the rail, this movement of the lever along the inclined end portion serving to swing the lever vertically, so that its forward end is swung vertically and downwardly. A cord 18 is attached to the forward end of the lever and passes to the cab of the locomotive and around a pulley 19 therein and thence forwardly to a helical spring 20, which in turn is attached to the whistle-lever 21. A second cord 22 is attached to the first cord and is connected to a handle 23 within the cab for operating the whistle manually. A guide 24 is attached to the beam 13 and extends downwardly at the sides of the lever and at the sides of the rail 12, so as to engage and move from the rails any material that may have fallen against it, the cross-bar 25 at the bottom of the guidearms serving to limit the downward movement of the lever when the latter is out of contact with the rail 12, it being understood that the lever is suitably weighted to insure this position. The guide referred to is formed integral with a snow-plow 27, which extends forwardly and downwardly from the beam of the locomotive-truck into close proximity to the rail 12, so as to engage and remove any snow that may lie thereon and which would interfere with the correct operation of the lever.

What is claimed is 1. The combination with a railway-track and a locomotive thereon, of a supplemental rail disposed longitudinally of the track, a hanger suspended from the truck of the locomotive, a lever pivoted in the hanger and disposed to hang in position to strike the supplemental rail and move thereonto, a guide for said lever constructed and arranged to limit the downward movement of its contacting end,

said guide being in position to straddle the supplemental rail, a whistle upon the locomotive and a cord connecting the lever and whistle for operating the latter when the lever moves onto the supplemental rail.

2. The combination With a railway-track and a locomotive thereon, of a supplemental rail disposed longitudinally of the track, a hanger suspended from the truck of the locomotive, a lever pivoted in the hanger and disposed to hang in position to strike the supplemental rail and move thereonto, a guide for said lever constructed and arranged to limit the downward movement of the contacting-end of the lever, said guide being in position to straddle the supplemental rail, a snov -plow formed integral with said guide and projecting from the truck in position to engage and remove snow from the supplemental rail, a Whistle for the locomotive, and a cord connecting the lever with the whistle for operating the latter.

In testimony whereof I affix my signature in presence of two Witnesses.
